An easier toolset

It is very hard to measure how easy a toolset is to use just based on "ease of use". You have to consider the content that it is trying to generate. Most of the time you even have to break the toolsets down into independent functions in order to just make a fair comparison between different toolsets.

For example, back in the old days of Quake you could compare id's Quake editor with the other toolsets such as Worldcraft, QERadient or Quark. Since all those toolsets where designed to generate the same basic content it is very easy to compare them and say which one of better as far as ease of use.

But how do you compare QERadient with NWN Toolset? You really can't. They are two totally different pieces of software trying to generate game content on two totally different levels. Both scripting and level design in Quake is hard and involved. The scripting wasn't really scripting but the programming of the C/C++ DLL. The level building was all about placing cubes and complex 3d objects in your level while making sure faces were all correct to get the layout you wanted. This is all hard stuff to do but very powerful.
